During the Dual Setpoint Auto mode operation, when the room temperature exceeds the set temperature for cooling, the cooling operation is performed, and when the room temperature falls below the set temperature for heating, the heating operation is performed. (It can be used only when the setting of the indoor unit compatible with this function is valid.)
  • The settable temperature range is different for each operation mode.
    Settable temperature range
    Cool/Dry* 18 to 30 °C (64 to 88 °F) or 20 to 30 °C (68 to 88 °F)

    The lower limit of the setting temperature is different depending on the place of use.
    The heating set temperature range of 10°C to 15°C (48°F to 58°F) may not be settable, depending on the indoor unit model.
    Celsius display increases and decreases in 0.5°C steps and Fahrenheit display increases and decreases in 1°F steps.
  • Deadband:
    The deadband is the minimum value of the difference between the set temperature for cooling and the set temperature for heating (= cooling set temperature - heating set temperature) in Dual Setpoint Auto mode.
    The difference between the set temperature for cooling and heating in Dual Setpoint Auto mode can not be smaller than the deadband. The deadband is set in the indoor unit. To change this, consult an authorized service personnel.
